Title
(EN) HAND-ACTUATED SYRINGE WITH VACUUM CHAMBER FOR AUTO REFILL
(FR) SERINGUE MANUELLE À CHAMBRE À DÉPRESSION PERMETTANT UNE RECHARGE AUTOMATIQUE
Abstract
(EN)
A hand-activated syringe (14) is disclosed that uses a vacuum to retract a plunger (54) of the syringe (14) to draw fluid into a syringe body (18). A first seal (76) with the plunger (54) and a second seal (64) with the plunger (54) define a vacuum chamber (82). The spacing between the first seal (76) and the second seal (64) changes in response to the plunger (54) moving relative to the syringe body (18). Advancing the plunger (54) in a direction associated with a discharge stroke creates or increases a vacuum within the vacuum chamber (82) by increasing a spacing between the first seal (76) and the second seal (64). This vacuum thereafter may be used to retract the plunger (54) by decreasing a spacing between the first seal (76) and the second seal (64), and to thereby draw fluid into the syringe (14) from a fluid source (86).
(FR)
La présente invention concerne une seringue manuelle (14) utilisant une dépression pour tirer sur le piston (54) de la seringue (14) de façon à aspirer du fluide dans le corps de seringue (18). Un premier joint étanche (76) équipant le piston (54) et un second joint étanche (64) équipant le piston définissent une chambre à dépression (82). L'espacement entre le premier joint étanche (76) et le second joint étanche (64) varie en réaction au déplacement du piston (54) par rapport au corps de seringue (18). L'avancée du piston (54) dans un sens associé à une course de décharge crée ou augmente la dépression régnant dans la chambre à dépression (82) en augmentant l'espacement entre le premier joint étanche (76) et le second joint étanche (64). La dépression obtenue tire sur le piston (54) en faisant diminuer l'espacement entre le premier joint étanche (76) et le second joint étanche (64), de façon à aspirer le fluide dans la seringue (14) à partir d'une source de fluide (86).
